Droit - L2 : Use of force under the United Nations Charter and collective security

Over the past several centuries, States have created legal rules to regulate their conduct in a wide variety of areas : international personality, law of the sea, outer space, human rights, environmental protection, economic transactions and, of course, the use of force.

With the devastation brought by the two World Wars, States redoubled their efforts to impose legal restrictions to the use of force under the United Nations Charter.

The purpose of this course is, first of all, to determine which international legal norms relating to the use of force are in force. Secondly, we will explore several significant challenges to the collective security paradigm, including, among others, anticipatory self-defense, humanitarian interventions, counter-terrorism rules.
